Lee_e Posted June 14, 2015 Share Posted June 14, 2015 I'm after some expert advise from you boys.. I have just bought the supra and have noticed quite a severe brake judder at any speed. I thought straight away. Warped disc etc.. so I've had the front and rear brake discs and pads changed and it still does it ! I've had the new front brake discs skimmed and it's still vibrating like an ass. When the skimming was done we checked the front calipers for sticking and they are fine... I am guzumped as to what it could be... also I have had an audi garage (Mrs works there) .. check my bushes for play etc and nothing is wrong with them. The wheels vibrate between 70 and above mph so I will get balancing done. Any help would be great guys Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 14, 2015 Share Posted June 14, 2015 after market wheels? hub centric rings? Rust on hub faces no allowing new discs to seat square (although any garage should clean these up as a matter of course) Quote Link to comment Share on other sites More sharing options...
Tyson Posted June 14, 2015 Share Posted June 14, 2015 Could be a wheel bearing Quote Link to comment Share on other sites More sharing options...
bignum Posted June 14, 2015 Share Posted June 14, 2015 Did you have the discs skimmed on the car. Quote Link to comment Share on other sites More sharing options...

Lee_e Posted June 14, 2015 Author Share Posted June 14, 2015 (edited) Had the discs skimmed on the car but as I reported the issue before skimming they took the discs off and inspected them, cleaned hub surface then skimmed them. The wheels are aftermarket but are hubcentric and fit snug with no play. Wouldn't a wheel bearing make a noise/ vibrate all the time ? It only vibrates during breaking and anything over 75mph. Surely this wouldn't be wheel bearings ? Tyre tread is fine too. Not wearing Un even or low on tread.

evinX Posted June 14, 2015 Share Posted June 14, 2015 Brake fluid needs a change? don't know if brake lines could effect this either? Quote Link to comment Share on other sites More sharing options...
Lee_e Posted June 14, 2015 Author Share Posted June 14, 2015 Not sure on the brake fluid part but with the vibration being speed dependant and the amount of serious judder on the steering wheel I'd say it's not the fluid. Also.. it seems to feel at low speeds pulling up to a junction for example .. the brake pedal pulses up and down a few mm... that to me says warped disc or incorrect disc fitment does it not ?

Benjy Posted June 14, 2015 Share Posted June 14, 2015 Does the steering wheel shake? Is it the front discs you've had done? Quote Link to comment Share on other sites More sharing options...
Lee_e Posted June 14, 2015 Author Share Posted June 14, 2015 Steering wheel shakes. Shakes worse at higher speeds when braking. I've had the fronts removed ... pistons and sliders checked and re greased. Hub cleaned and fitted back then skimmed on the car. Could the front discs still be warped if they have been skimmed ? I watched them skimming and one side was slightly warped as it missed the cutter in one spot. We moved the cutter in a notch on the spot it was missing until it cleared ... could it still be warped ? They are literally 2 week old discs. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 14, 2015 Share Posted June 14, 2015 Sounds to me like the disc(s) are not sitting flush on the hubs, providing the wheel centre bore is correct, the tyres are round, wheel weights in place. Quote Link to comment Share on other sites More sharing options...
Lee_e Posted June 14, 2015 Author Share Posted June 14, 2015 I'm hopefully getting SRD to check it over for me soonish so I'm hoping it's something simple but I think if it's not hub related then I will be buying a set of discs and pads and go from there me thinks.

Dnk Posted August 12, 2015 Share Posted August 12, 2015 (edited) Check the discs off the car on a surface plate with a DTI or Verdict clock, or bolt them on and check them fitted to the hub Edited August 12, 2015 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Lee_e Posted August 12, 2015 Author Share Posted August 12, 2015 New original toyota discs and pads sorted it bud. Quote Link to comment Share on other sites More sharing options...
